Yeah, that is why I always hit the ground around smaller enemies otherwise it's meh,
though the melee attack does help a lot - the Autocannon one wrecks boss/big enemies.

I personally find the amount of rockets on the Minigun one should REALLY be increased

I still like the MG exosuit more than the auto cannon variant. Even with the nerfed rockets I find it better against chaff and chargers.

The autocannon mech is pretty good, if you use it well.

But they are going to give us customized loadouts,
at some point & buff their health (all confirmed stuff).
